What other Titan Class Transformers do you want?

Since 2013 with Metroplex's release we have gotten every Cityformer from G1 except Scorponok

Not quite. There is at least one other Cityformer - Grandus. In fact if the Micromaster toys are are still getting made, it would be quite appropriate for him to get made since he turned into a city/battle base for Micromaster figures.

Of course if the Titan doesn't need to have a G1-toy origin then they could do Metrobase who has G1 fiction origins and is now in the Movie Continuity as well. A G1 version based on the Metroplex toy would be easy to do, though I would love to see them try and do the Movie Continuity version.

Maybe a Primus/Cybertron but if they do that, it might be a pulse thing, I don't think it would go as well as Unicron though.

Yeah if they were to make a Primus, I would want him to be on par in size with the new Unicron, much like the two gods from the Unicron Wars trilogy toys are. Maybe if they dropped the amount of orders from 8000 to 5000 they may accomplish it, since many of those that have bought Unicron would like to have his nemesis too.
